Check hydraulic hoses and lines daily for signs of leaks. Replace leaking hoses. Refer to Section Removing Master
Cylinder Hose, page 160 and Section Replace Master Cylinder Hose from Multi-Coupler for hold-down lift system.

WARNING
• Avoid high-pressure fluids. Escaping fluid can
penetrate the skin causing serious injury.
• Relieve pressure before disconnecting hydraulic
lines.
• Tighten all connections before applying pressure.
Keep hands and body away from pin- holes and
nozzles which eject fluids under high pressure.
• If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor
who is familiar with this type of injury or gangrene
may result.

WARNING
• Use a piece of cardboard or paper to search for
leaks.
IMPORTANT:
• Keep hydraulic coupler tips and connectors
clean. Dust, dirt, water and foreign material are
the major causes of hydraulic system damage.
• DO NOT attempt to service hydraulic system in
the field. Precision fits require WHITE ROOM
CARE during overhaul.
